Generate Docs Compatibility Matrix

[danehans]

Currently, the compatibility matrix is manually maintained. With #609, we have most of the information required to update the compatibility matrix for a release. Consider creating a make target that updates the matrix by scraping the output of envoy-gateway version and grep'ing $KIND_NODE_TAG from tools/hack/create-cluster.sh.

xref #681 for supporting multiple k8s releases.
